10701040 Murphy Temperature Swichgage SDB500EX

Murphy SDB500EX Direct Mount Temperature Swichgage

The SDB Series are direct-mounting temperature Swichgage devices. They provide an accurate direct-reading gage with an adjustable limit switch to activate alarms and/or shutdown. A knob on front of the Swichgage instrument allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element. The most common use of the SDB Series is to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate overloading or lean fuel mixtures, or use the SDB to help coordinate loads on twin-engine installations.

This product may vary on delivery times, as factories do not guarantee production due to lack of raw materials.
